Back in the days when TiVo was a thing, I built a MythTV box including all the troubleshooting of a capture card, X windows settings, getting a remote to work, etc. to the point where my non-tech spouse could use it like a set top box. It even looked like a set top box. This was when Netflix was DVD by mail.

The last Windows laptop I bought bricked itself in a week, the Amazon stick needed constant reboots, I don't care about side-loading apps/widgets/software on my devices - I want them to be like my refrigerator and just work. AppleTV devices are much better than others. Once you're in the Apple walled garden things are much easier on me as an end user. There are seamless transitions from device to device if I want, sharing between them is a breeze. Sure other platforms are "open" or might have more advanced features, but I don't want to waste my time doing tech support having the BeenThereDoneThat™ patch.

Edit to add: "open" usually just means you have countless versions of "standards" to try and get things to interoperate. I deal enough with that at work to be turned off from dealing with that at home when I just want to chill and consume whatever nonsense I'm into.
